Main trade-off
Denon AVR-S970H
There are no front-channel pre-outs for a stereo power amplifier.
Head-to-head
Denon AVR-S970H vs AVR-X1800H: S970H keeps two displays connected, X1800H supports a separate front amp
The short answer
Choose AVR-S970H for a TV and projector that stay connected. Choose AVR-X1800H for MultEQ XT or a separate amplifier driving the front pair. Neither is a complete upgrade over the other. They share the same seven-channel and six-input limits.
Before you choose
The reasoning and the trade-offs
A two-display room and a front power amp need a third option
S970H has the second HDMI output but no front pre-outs. X1800H has front pre-outs but only one display output. If both connections are essential, neither satisfies the whole room.
What this is based on
Required: 2 HDMI outputs and 2 front main-channel pre-outs. S970H = 2 outputs and 0 pre-outs. X1800H = 1 output and 2 front pre-outs.
Main trade-off
Denon AVR-X1800H
Only one HDMI display output is available.

What matters in practice
The differences that matter
A two-display room and a front power amp need a third option
S970H has the second HDMI output but no front pre-outs. X1800H has front pre-outs but only one display output. If both connections are essential, neither satisfies the whole room.
How we reached this conclusion
Required: 2 HDMI outputs and 2 front main-channel pre-outs. S970H = 2 outputs and 0 pre-outs. X1800H = 1 output and 2 front pre-outs.
The X-series label does not increase this speaker count
Both receivers process and amplify seven main channels. A five-speaker base and two heights fit equally. A four-height plan is two main channels beyond either model.
How we reached this conclusion
Both provide 7 main channels. A 5.1.2 layout uses 5 + 2 = 7. A 5.1.4 layout uses 5 + 4 = 9, exceeding either receiver by 2.
Three fast devices leave the same three ordinary inputs free
A gaming PC and two consoles can occupy the three 4K120 inputs on either model. That leaves three other HDMI sockets for a disc player, streamer or another source. The model choice does not change that source budget.
How we reached this conclusion
6 total HDMI inputs - 3 4K120 sources = 3 remaining HDMI inputs on each receiver. Format compatibility and input settings still apply.

Denon AVR-S970H
Supports your setup
Supports 5.1.2 using the receiver's own amplifiers. Connects 3 HDMI devices, including 1 at 4K/120Hz.
Denon AVR-X1800H
Supports your setup
Supports 5.1.2 using the receiver's own amplifiers. Connects 3 HDMI devices, including 1 at 4K/120Hz.
A powered subwoofer is separate from the speaker-channel count. This checks one main room. Zone 2, bi-amping and unusual speaker assignments need another manual check. Allow ventilation space and confirm HDMI settings, cables and speaker impedance before installing.
Choice A

Meaningful differences
What changes the fit
| What changes | Denon AVR-S970H | Denon AVR-X1800H | Why it matters |
|---|---|---|---|
| HDMI display outputs | 2 | 1 | S970H is the direct fit for two connected displays. |
| Main-channel pre-outs | None | Front left and right | X1800H can reuse a separate front-channel power amplifier. |
| Included calibration | Audyssey MultEQ | Audyssey MultEQ XT | The X1800H adds the XT calibration tier rather than a second display output. |
| Source inputs | 6 HDMI, including 3 with 4K120 | 6 HDMI, including 3 with 4K120 | Both accommodate the same total and high-frame-rate source counts. |
| Speaker layouts | 5.1, 7.1 or 5.1.2 | 5.1, 7.1 or 5.1.2 | Neither can process a 5.1.4 system. |
What you give up
Every choice has a cost
If you choose Denon AVR-S970H
- Its Audyssey version is MultEQ, below the XT tier in X1800H.
If you choose Denon AVR-X1800H
- Its X-series name does not add speaker channels or HDMI inputs.
Recommendation switch
The decision flips if...
Two displays matter and all speakers use internal amps
Choose Denon AVR-S970H. S970H supplies the second HDMI output.
One display is enough and I need front pre-outs
Choose Denon AVR-X1800H. X1800H supplies the stereo amplifier connection.
I need both two displays and front pre-outs
Choose neither. Neither model provides this combination.
What matters in practice
How to make the call
Treat this as a crossed feature choice
S970H has a connection that X1800H does not, despite the latter belonging to the X series. If a projector is part of your room, losing the second display output can be more inconvenient than any calibration change. Put the rear-panel requirements ahead of the model hierarchy.
Decide whether front pre-outs are useful now
X1800H can connect an existing stereo amp directly to the front channels. That is concrete value if you own one or have chosen one. If all speakers will stay on the receiver's internal amps, those sockets may never be used.
An offer is only good when it covers the room
Check the exact current Amazon prices after deciding which output arrangement works. A cheaper receiver can become awkward if it forces a display switch or removes a planned amplifier connection. Where you need both features, expand the shortlist rather than choosing the least inconvenient compromise.
What this comparison cannot tell you
- These are US connection and speaker-layout checks. We have not measured amplifier output, room-correction results or sound quality. HDMI format, firmware and display compatibility still need checking.
